BACKGROUND OF THE INVENTION

This invention relates to novel pyrimidine derivatives that are useful in the treatment of abnormal cell growth, such as cancer, in mammals. This invention also relates to a method of using such compounds in the treatment of abnormal cell growth in mammals, especially humans, and to pharmaceutical compositions containing such compounds.

It is known that a cell may become cancerous by virtue of the transformation of a portion of its DNA into an oncogene (i.e., a gene which, on activation, leads to the formation of malignant tumor cells). Many oncogenes encode proteins that are aberrant tyrosine kinases capable of causing cell transformation. Alternatively, the overexpression of a normal proto-oncogenic tyrosine kinase may also result in proliferative disorders, sometimes resulting in a malignant phenotype.

Receptor tyrosine kinases are enzymes which span the cell membrane and possess an extracellular binding domain for growth factors such as epidermal growth factor, a transmembrane domain, and an intracellular portion which functions as a kinase to phosphorylate specific tyrosine residues in proteins and hence to influence cell proliferation. Other receptor tyrosine kinases include c-erbB-2, c-met, tie-2, PDGFr, FGFr, and VEGFR. It is known that such kinases are frequently aberrantly expressed in common human cancers such as breast cancer, gastrointestinal cancer such as colon, rectal or stomach cancer, leukemia, and ovarian, bronchial or pancreatic cancer. It has also been shown that epidermal growth factor receptor (EGFR), which possesses tyrosine kinase activity, is mutated and/or overexpressed in many human cancers such as brain, lung, squamous cell, bladder, gastric, breast, head and neck, oesophageal, gynecological and thyroid tumors.

Accordingly, it has been recognized that inhibitors of receptor tyrosine kinases are useful as selective inhibitors of the growth of mammalian cancer cells. For example, erbstatin, a tyrosine kinase inhibitor, selectively attenuates the growth in athymic nude mice of a transplanted human mammary carcinoma that expresses epidermal growth factor receptor tyrosine kinase (EGFR) but is without effect on the growth of another carcinoma that does not express the EGF receptor. Thus, selective inhibitors of certain receptor tyrosine kinases, are useful in the treatment of abnormal cell growth, in particular cancer, in mammals. In addition to receptor tyrosine kinses, selective inhibitors of certain non-receptor tyrosine kinases, such as FAK (focal adhesion kinase), lck, src, abl or serine/threonine kinases (e.g.: cyclin dependent kinases, are useful in the treatment of abnormal cell growth, in particular cancer, in mammals. FAK is also known as the Protein-Tyrosine Kinase 2, PTK2.

Convincing evidence suggests that FAK, a cytoplasmic, non-receptor tyrosine kinase, plays an essential role in cell-matrix signal transduction pathways (Clark and Brugge 1995, Science 268: 233–239) and its aberrant activation is associated with an increase in the metastatic potential of tumors (Owens et al. 1995, Cancer Research 55: 2752–2755). FAK was originally identified as a 125 kDa protein highly tyrosine-phosphorylated in cells transformed by v-Src. FAK was subsequently found to be a tyrosine kinase that localizes to focal adhesions, which are contact points between cultured cells and their underlying substratum and sites of intense tyrosine phosphorylation. FAK is phosphorylated and, thus, activated in response to extracellular matrix (ECM)-binding to integrins. Recently, studies have demonstrated that an increase in FAK mRNA levels accompanied invasive transformation of tumors and attenuation of the expression of FAK (through the use of antisense oligonucleotides) induces apoptosis in tumor cells (Xu et al. 1996, Cell Growth and Diff. 7: 413–418). In addition to being expressed in most tissue types, FAK is found at elevated levels in most human cancers, particularly in highly invasive metastases.

Various compounds, such as styrene derivatives, have also been shown to possess tyrosine kinase inhibitory properties. Five European patent publications, namely EP 0 566 226 A1 (published Oct. 20, 1993), EP 0 602 851 A1 (published Jun. 22, 1994), EP 0 635 507 A1 (published Jan. 25, 1995), EP 0 635 498 A1 (published Jan. 25, 1995), and EP 0 520 722 A1 (published Dec. 30, 1992), refer to certain bicyclic derivatives, in particular quinazoline derivatives, as possessing anti-cancer properties that result from their tyrosine kinase inhibitory properties.

Also, World Patent Application WO 92/20642 (published Nov. 26, 1992), refers to certain bis-mono and bicyclic aryl and heteroaryl compounds as tyrosine kinase inhibitors that are useful in inhibiting abnormal cell proliferation. World Patent Applications WO96/16960 (published Jun. 6, 1996), WO 96/09294 (published Mar. 6, 1996), WO 97/30034 (published Aug. 21, 1997), WO 98/02434 (published Jan. 22, 1998), WO 98/02437 (published Jan. 22, 1998), and WO 98/02438 (published Jan. 22, 1998), also refer to substituted bicyclic heteroaromatic derivatives as tyrosine kinase inhibitors that are useful for the same purpose.

U.S. patent application Ser. No. 60/435,670, filed Dec. 20, 2002 relates to a broad class of novel pyrimidine derivatives that are selective inhibitors of FAK. As such, these compounds are useful in the treatment of abnormal cell growth.

Accordingly, a need exists for additional selective inhibitors of certain receptor and non-receptor tyrosine kinases, useful in the treatment of abnormal cell growth, such as cancer, in mammals. The present invention provides for novel pyrimidine derivatives that are selective inhibitors of the non-receptor tyrosine kinase, FAK, and are useful in the treatment of abnormal cell growth.

Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically-labelled compounds of Formula 1 of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the Schemes and/or in the Examples and Preparations below, by substituting a readily available isotopically-labelled reagent for a non-isotopically-labelled reagent.

The present invention also relates to the pharmaceutically acceptable acid addition salts of compounds of the formula 1. The acids which are used to prepare the pharmaceutically acceptable acid addition salts of the aforementioned base compounds of this invention are those which form non-toxic acid addition salts, i.e., salts containing pharmacologically acceptable anions, such as the chloride, bromide, iodide, nitrate, sulfate, bisulfate, phosphate, acid phosphate, acetate, lactate, citrate, acid citrate, tartrate, bitartrate, succinate, maleate, fumarate, gluconate, saccharate, benzoate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate and pamoate [i.e., 1,1′-methylene-bis-(2-hydroxy-3-naphthoate)]salts.

In a more preferred embodiment cancer is selected a solid tumor, such as, but not limited to, breast, lung, colon, brain, prostate, stomach, pancreatic, ovarian, skin (melanoma), endocrine, uterine, testicular, and bladder.

The compounds of the present invention may also be useful in the treatment of additional disorders in which aberrant expression ligand/receptor interactions or activation or signalling events related to various protein tyrosine kinases, are involved. Such disorders may include those of neuronal, glial, astrocytal, hypothalamic, and other glandular, macrophagal, epithelial, stromal, and blastocoelic nature in which aberrant function, expression, activation or signalling of the erbB tyrosine kinases are involved. In addition, the compounds of the present invention may have therapeutic utility in inflammatory, angiogenic and immunologic disorders involving both identified and as yet unidentified tyrosine kinases that are inhibited by the compounds of the present invention.

The term “treating”, as used herein, unless otherwise indicated, means reversing, alleviating, inhibiting the progress of, or preventing the disorder or condition to which such term applies, or one or more symptoms of such disorder or condition. The term “treatment”, as used herein, unless otherwise indicated, refers to the act of treating as “treating” is defined immediately above.

The present invention also provides a pharmaceutical composition comprising a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, as hereinbefore defined in association with a pharmaceutically acceptable adjuvant, diluent or carrier.

The invention further provides a process for the preparation of a pharmaceutical composition of the invention which comprises mixing a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, as hereinbefore defined with a pharmaceutically acceptable adjuvant, diluent or carrier.

For the above-mentioned therapeutic uses the dosage administered will, of course, vary with the compound employed, the mode of administration, the treatment desired and the disorder indicated.

Combining 3 with an equimolar amount of a Lewis Acid at temperatures ranging from −15 to 45° C. for a time period of 10–60 minutes in an inert solvent (or solvent mixture) followed by addition of 2 and a suitable base provides after the period of 1–24 h the intermediate 4-chloropyrimidine (4) in high yields. Examples of inert solvents include but are not limited to THF, 1,4-dioxane, n-BuOH, i-PrOH, dichloromethane and 1,2-dichloroethane. Examples of suitable bases employed may include but are not limited to (i) non-nucleophilic organic bases for example triethylamine or diisopropylethylamine (ii) inorganic bases such as potassium carbonate or cesium carbonate or (iii) resin bound bases such as MP-carbonate.

Examples of Lewis Acids include but are not limited to halide salts of magnesium, copper, zinc, tin or titanium. In the next reaction, intermediate 4 is reacted with an amine of the formula 5 either neat or in the presence of an inert solvent (or solvent mixture) at temperatures ranging from 0 to 150° C. to provide the compounds of formula 1. Optionally this reaction can be run in the presence of a suitable base. Examples of suitable solvents for this reaction include but are not limited to THF, 1,4-dioxane, DMF, N-methyl-pyrrolidinone, EtOH, n-BuOH, i-PrOH, dichloromethane, 1,2-dichloroethane, DMSO or acetonitrile. Suitable bases are as outlined above.

Compounds of the present invention may be synthetically transformed into other compounds of the invention by techniques known to those skilled in the art. Simply for illustrative purposes and without limitation, such methods include:

a) removal of a protecting group by methods outlined in T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis”, Second Edition, John Wiley and Sons, New York, 1991; e.g., emoval of a BOC protecting group with an acid source such as HCl or trifluoroacetic acid.

b) displacement of a leaving group (halide, mesylate, tosylate, etc) with functional groups such as but not limited to a primary or secondary amine, thiol or alcohol to form a secondary or tertiary amine, thioether or ether, respectively.

c) treatment of phenyl (or substituted phenyl) carbamates with primary of secondary amines to form the corresponding ureas as in Thavonekham, B et. al. Synthesis (1997), 10, p1189;

d) reduction of propargyl or homopropargyl alcohols or N-BOC protected primary amines to the corresponding E-allylic or E-homoallylic derivatives by treatment with sodium bis(2-methoxyethoxy)aluminum hydride (Red-Al) as in Denmark, S. E.; Jones, T. K. J. Org. Chem. (1982) 47, 4595–4597 or van Benthem, R. A. T. M.; Michels, J. J.; Speckamp, W. N. Synlett (1994), 368–370;

e) reduction of alkynes to the corresponding Z-alkene derivatives by treatment hydrogen gas and a Pd catalyst as in Tomassy, B. et. al. Synth. Commun. (1998), 28, p1201

f) treatment of primary and secondary amines with an isocyanate, acid chloride (or other activated carboxylic acid derivative), alkyl/aryl chloroformate or sulfonyl chloride to provide the corresponding urea, amide, carbamate or sulfonamide;

g) reductive amination of a primary or secondary amine using an aldehyde or ketone and an appropriate reducing reagent.

h) treatment of alcohols with an isocyanate, acid chloride (or other activated carboxylic acid derivative), alkyl/aryl chloroformate or sulfonyl chloride to provide the corresponding carbamate, ester, carbonate or sulfonic acid ester.

Amines of the formula 5 may be purchased and used directly or alternatively be prepared by one skilled in the art using ordinary chemical transformations. For example; arylalkylamines or heteroarylalkylamines may be prepared from the corresponding nitrile by catalytic hydrogenation using catalysts such as Pd/C or Raney Nickel or by lithium aluminum hydride reduction, (see Rylander, Catalytic Hydrogenation in Organic Synthesis, Academic Press, 1979).

The nitrile starting materials can be either purchased or prepared from the corresponding aryl/heteroaryl bromide, iodide or triflate and Zn(CN)2 using Pd coupling conditions found in Tschaen, D. M., et. al Synthetic Communications (1994), 24, 6, pp 887–890.

Alternatively, benzylamines or heteroarylmethylamines can be prepared by reacting the appropriate arylalkyl or heteroarylalkyl halide and the potassium salt of (BOC)₂NH (reference) and subsequent removal of the BOC groups with acid.

Amines, protected forms of amines, precursors to amines and precursors to the protected forms of amines of formula 5 can be prepared by combining the appropriate alkyne, or alkenyl stannane, alkenyl borane, alkenyl boronic acid, boronic ester with the appropriate aryl or heteroaryl bromide, iodide or triflate using Pd coupling conditions as found in Tsuji, J.; Palladium Reagents and Catalysis, John Wiley and Sons 1999 and references cited therein.

Appropriately protected amines of formula 5 may be converted to different amines of formula 5 according to methods familiar to those skilled in the art for exampleas but limited to:

(a) oxidation of a thioether to a sulfoxide or sulfone.

(b) N-alkylation of a sulfanilide can be achieved under phase transfer using conditions described by Brehme, R. “Synthesis”, (1976), pp113–114.

As understood by those skilled in the art, the chemical transformation to convert an aryl halide or triflate or heteroaryl halide or triflate to an aromatic or heteroaromatic amine may be carried out using conditions currently outlined in the literature, see Hartwig, J. F.: “Angew. Chem. Int. Ed.” (1998), 37, pp. 2046–2067, Wolfe, J. P.; Wagaw, S.; Marcoux, J. F.; Buchwald, S. L.; “Acc. Chem. Res.”, (1998), 31, pp 805–818, Wolfe, J. P.; Buchwald, S. L.; “J. Org. Chem.”, (2000), 65, pp 1144–1157, Muci, A. R.; Buchwald, S. L.; “Topics in Current Chemistry” (2002), pp131–209 and references cited therein. Further, as understood by those skilled in the art, these same aryl or heteroaryl amination chemical transformations may alternatively be carried out on nitrile (or primary amide) precursors which provide amines of the formula 5 after nitrile (or amide) reduction. Protected amines of formula 5 may be further converted to different amines of formula 5 according to methods familiar to those skilled in the art.

5. Dilute on ice, FAKcd protein to 1:1000 in Kinase Phosphorylation Buffer. Dispense 30 ul per well.

6. Note: Linearity and the appropriate dilution must be pre-determined for each batch of protein. The enzyme concentration selected should be such that quantitation of the assay signal will be approximately 0.8–1.0 at OD450, and in the linear range of the reaction rate.

7. Prepare both a No ATP control (noise) and a No Compound Control (Signal):

8. (Noise) One blank row of wells receives 10 ul of 1:5 diluted compounds in DMSO, 80 ul of Phosphorylation buffer (minus ATP), and 30 ul FAKcd solution.

FAK cell-based Protocol for selectivity of kinase-dependent phosphoFAKY397

Procedure:

An inducible FAK cell-based assay in ELISA format for the screening of chemical matter to identify tyrosine kinase specific inhibitors was developed. The cell-based assay exploits the mechanism of the GeneSwitch™ system (InVitrogen) to exogenously control the expression and phosphorylation of FAK and the kinase-dependent autophosphorylation site at residue Y397.

Inhibition of the kinase-dependent autophosphorylation at Y397 results in a reduced absorbance signal at OD450. The signal is typically 0.9 to 1.5 OD450 units with the noise falling in the range of 0.08 to 0.1 OD450 units. The values are reported as IC50s, uM concentration.

On day 1, grow A431∘FAKwt in T175 flasks. On the day prior to running the FAK cell-assay, seed A431∘FAKwt cells in growth media on 96-well U-bottom plates. Allow cells to sit at 37° C., 5% CO2 for 6 to 8 hours prior to FAK induction. Prepare Mifepristone stock solution of 10 uM in 100% Ethanol. The stock solution is subsequently diluted to 10× of the final concentration in Growth Media. Transfer 10 ul of this dilution (final concentration of 0.1 nM Mifepristone) into each well. Allow cells to sit at 37° C., 5% CO2 overnight (12 to 16 hours). Also, prepare control wells without Mifepristone induction of FAK expression and phosphorylation.

On day 2, coat Goat Anti-Rabbit plate(s) with 3.5 ug/ml of phosphospecific FAKpY397 polyclonal antibody prepared in SuperBlock TBS buffer, and allow plate(s) to shake on a plate shaker at room temperature for 2 hours. Optionally, control wells may be coated with 3.5 ug/ml of control Capture antibody (Whole Rabbit IgG molecules) prepared in SuperBlock TBS. Wash off excess FAKpY397 antibody 3 times using buffer. Block Anti-FAKpY397 coated plate(s) with 200 ul per well of 3%BSA/0.5%Tween Blocking buffer for 1 hour at room temperature on the plate shaker. While the plate(s) are blocking, prepare compound stock solutions of 5 mM in 100% DMSO. The stock solutions are subsequently serially diluted to 100× of the final concentration in 100% DMSO. Make a 1:10 dilution using the 100× solution into growth media and transfer 10 ul of the appropriate compound dilutions to each well containing either the FAK induced or uninduced control A431 cells for 30 minutes at 37° C., 5% CO2. Prepare RIPA lysis buffer (50 mM Tris-HCl, pH7.4, 1% NP-40, 0.25% Na-deoxycholate, 150 mM NaCl, 1 mM EDTA, 1 mM Na3VO4, 1 mM NaF, and one Complete™ EDTA-free protease inhibitor pellet per 50 ml solution). At the end of 30 minutes compound treatment, wash off compound 3 times using TBS-T wash buffer. Lyse cells with 100 ul/well of RIPA buffer.

To the coated plate, remove blocking buffer and wash 3 times using TBS-T wash buffer. Using a 96-well automated microdispenser, transfer 100 ul of whole cell-lysate (from step 6) to the Goat Anti-Rabbit FAKpY397 coated plate(s) to capture phosphoFAKY397 proteins. Shake at room temperature for 2 hours. Wash off unbound proteins 3 times using TBS-T wash buffer. Prepare 0.5 ug/ml (1:2000 dilution) of UBI αFAK detection antibody in 3% BSA/0.5% Tween blocking buffer. Dispense 100 ul of UBI αFAK solution per well and shake for 30 minutes at room temperature. Wash off excess UBI αFAK antibody 3 times using TBS-T wash buffer. Prepare 0.08 ug/ml (1:5000 dilution) of secondary Anti-Mouse Peroxidase (Anti-2MHRP) conjugated antibody. Dispense 100 ul per well of the Anti-2MHRP solution and shake for 30 minutes at room temperature. Wash off excess Anti-2MHRP antibody 3 times using TBS-T wash buffer. Add 100 ul per well of room temperature TMB substrate solution to allow for color development. Terminate the TMB reaction with 100 ul per well of TMB stop solution (0.09M H2SO4) and quantitate the signal by measurement of absorbance at 450 nm on the BioRad microplate reader.

Additional FAK cell assays are hereby incorporated by reference from Pfizer Attorney Docket No. PC11699 entitled “INDUCIBLE FOCAL ADHESION KINASE CELL ASSAY”.

In a preferred embodiment, the compounds of the present invention have an in vivo activity as determined by a kinase assay, e.g., such as that described herein, of less than 100 nM. Preferably, the compounds have an IC₅₀ of less than 25 nM in the kinase assay, and more preferably less than 10 nM. In a further preferred embodiment, the compounds exhibit an IC₅₀ in a FAK cell based assay, e.g., such as that described herein, of less than 1 □M, more preferably less than 100 nM, and most preferably less than 25 nM.

Administration of the compounds of the present invention (hereinafter the “active compound(s)”) can be effected by any method that enables delivery of the compounds to the site of action. These methods include oral routes, intraduodenal routes, parenteral injection (including intravenous, subcutaneous, intramuscular, intravascular or infusion), topical, and rectal administration.

The amount of the active compound administered will be dependent on the subject being treated, the severity of the disorder or condition, the rate of administration, the disposition of the compound and the discretion of the prescribing physician. However, an effective dosage is in the range of about 0.001 to about 100 mg per kg body weight per day, preferably about 1 to about 35 mg/kg/day, in single or divided doses. For a 70 kg human, this would amount to about 0.05 to about 7 g/day, preferably about 0.2 to about 2.5 g/day. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, provided that such larger doses are first divided into several small doses for administration throughout the day.

The active compound may be applied as a sole therapy or may involve one or more other anti-tumour substances, for example those selected from, for example, mitotic inhibitors, for example vinblastine; alkylating agents, for example cis-platin, carboplatin and cyclophosphamide; anti-metabolites, for example 5-fluorouracil, cytosine arabinoside and hydroxyurea, or, for example, one of the preferred anti-metabolites disclosed in European Patent Application No. 239362 such as N-(5-[N-(3,4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino]-2-thenoyl)-L-glutamic acid; growth factor inhibitors; cell cycle inhibitors; intercalating antibiotics, for example adriamycin and bleomycin; enzymes, for example interferon; and anti-hormones, for example anti-estrogens such as Nolvadex□ (tamoxifen) or, for example anti-androgens such as Casodex□ (4′-cyano-3-(4-fluorophenylsulphonyl)-2-hydroxy-2-methyl-3′-(trifluoromethyl)propionanilide). Such conjoint treatment may be achieved by way of the simultaneous, sequential or separate dosing of the individual components of the treatment.

The pharmaceutical composition may, for example, be in a form suitable for oral administration as a tablet, capsule, pill, powder, sustained release formulations, solution, suspension, for parenteral injection as a sterile solution, suspension or emulsion, for topical administration as an ointment or cream or for rectal administration as a suppository. The pharmaceutical composition may be in unit dosage forms suitable for single administration of precise dosages. The pharmaceutical composition will include a conventional pharmaceutical carrier or excipient and a compound according to the invention as an active ingredient. In addition, it may include other medicinal or pharmaceutical agents, carriers, adjuvants, etc.

Exemplary parenteral administration forms include solutions or suspensions of active compounds in sterile aqueous solutions, for example, aqueous propylene glycol or dextrose solutions. Such dosage forms can be suitably buffered, if desired.

Suitable pharmaceutical carriers include inert diluents or fillers, water and various organic solvents. The pharmaceutical compositions may, if desired, contain additional ingredients such as flavorings, binders, excipients and the like. Thus for oral administration, tablets containing various excipients, such as citric acid may be employed together with various disintegrants such as starch, alginic acid and certain complex silicates and with binding agents such as sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful for tableting purposes. Solid compositions of a similar type may also be employed in soft and hard filled gelatin capsules. Preferred materials, therefor, include lactose or milk sugar and high molecular weight polyethylene glycols. When aqueous suspensions or elixirs are desired for oral administration the active compound therein may be combined with various sweetening or flavoring agents, coloring matters or dyes and, if desired, emulsifying agents or suspending agents, together with diluents such as water, ethanol, propylene glycol, glycerin, or combinations thereof.

Methods of preparing various pharmaceutical compositions with a specific amount of active compound are known, or will be apparent, to those skilled in this art. For examples, see Remington's Pharmaceutical Sciences, Mack Publishing Company, Easter, Pa., 15th Edition (1975).

The examples and preparations provided below further illustrate and exemplify the compounds of the present invention and methods of preparing such compounds. It is to be understood that the scope of the present invention is not limited in any way by the scope of the following examples and preparations. In the following examples molecules with a single chiral center, unless otherwise noted, exist as a racemic mixture. Those molecules with two or more chiral centers, unless otherwise noted, exist as a racemic mixture of diastereomers. Single enantiomers/diastereomers may be obtained by methods known to those skilled in the art.

Where HPLC chromatography is referred to in the preparations and examples below, the general conditions used, unless otherwise indicated, are as follows. The column used is a ZORBAX□ RXC18 column (manufactured by Hewlett Packard) of 150 mm distance and 4.6 mm interior diameter. The samples are run on a Hewlett Packard-1100 system. A gradient solvent method is used running 100 percent ammonium acetate/acetic acid buffer (0.2 M) to 100 percent acetonitrile over 10 minutes. The system then proceeds on a wash cycle with 100 percent acetonitrile for 1.5 minutes and then 100 percent buffer solution for 3 minutes. The flow rate over this period is a constant 3 ml/minute.

In the following examples and preparations, “Et” means ethyl, “Ac” means acetyl, “Me” means methyl, and “Bu” means butyl.

EXAMPLES

General Methods:

Preparation of 5-nitro-oxindole:

To a solution of oxindole (26 g) in 100 mL of concentrated sulfuric acid at −15° C. was added fuming nitric acid (8.4 mL) dropwise. Careful attention was paid to maintain the reaction temperature at −15° C. After the addition was complete, the reaction was stirred for 30 minutes and then poured into ice water. A yellow precipitate was formed which was isolated by filtration to provide 34 grams (98%) of 5-nitro oxindole.

To a solution of 5-nitro-oxindole (25 g) in 120 mL of dimethylacetamide in a Parr bottle was added 10% Pd/C (0.5 g). The mixture was hydrogenated (40 psi H2) for 16 h. The catalyst was removed by filtration and the filtrate was diluted with ether (2L) to provide 5-amino-oxindole (10.5 g; 50%).

Preparation of 2,4-dichloro-5-trifluoromethylpyrimidine (3):

5-Trifluoromethyluracil (250 g, 1.39 mol) and phosphorous oxychloride (655 mL, 6.94 mol, 5 equiv) were charged to a 3 L 4-neck flask equipped with overhead stirrer, a reflux condenser, an addition funnel and an internal theromocouple. The contents were maintained under a nitrogen atmosphere as concentrated phosphoric acid (85 wt %, 9.5 mL, 0.1 equiv) was added in one portion to the slurry, resulting in a moderate exotherm. Diisopropylethylamine (245 mL, 1.39 mol, 1 equiv) was then added dropwise over 15 min at such a rate that the internal temperature of the reaction reached 85–90° C. by the end of the addition. By the end of the amine addition the reaction mixture was a homogenous light-orange solution. Heating was initiated and the orange solution was maintained at 100° C. for 20 h, at which time HPLC analysis of the reaction mixture indicated that the starting material was consumed. External heating was removed and the contents of the flask were cooled to 40° C. and then added dropwise to a cooled mixture of 3N HCl (5 L, 10 equiv) and diethyl ether (2 L) keeping the temperature of the quench pot between 10 and 15° C. The layers were separated, and the aqueous layer was extracted once with ether (1 L). The combined organic layers were combined, washed with water until the washes were neutral (5×1.5 L washes), dried with MgSO₄ and concentrated to provide 288 g (95% yield) of a light yellow-orange oil of 96% purity (HPLC). This material can be further purified by distillation (bp 109° C. at 79 mmHg).

Preparation of 5-(4-Chloro-5-trifluoromethyl-pyrimidin-2-ylamino)-1,3-dihydro-indol-2-one (4):

To a solution of 5-trifluoromethyl-2,4-dichloropyrimidine (214.8 g; 0.921 mol) in 1:1 DCE/tBuOH (1.240 L) was added Zinc chloride 1M solution in ether (1 eq; 0.921 L). After 0.5 hour, 5-amino-oxindole (124 g; 0.837 mol) was added followed by triethylamine (129.4 ml; 0.921 mol) keeping temperature at 25° C. The reaction was allowed to stir at room temperature overnight, then was concentrated and the product triturated from methanol as a yellow solid (224.3 g; 82%). ¹H NMR (DMSO-d₆, 400 MHz) □□3.29 (s, 2H), 6.76 (d, J=7.9 Hz, 2H), 7.39 (d, J=8.3 Hz), 7.51 (br s, 1H), 8.71 (s, 1H), 10.33 (s, 1H), 10.49 (s, 1H). ¹³C NMR (DMSO-d₆, 100 MHz) □ 177.0, 161.3, 158.7 (br), 140.7, 132.8, 126.9, 123.7 (q, J=268 Hz), 121.0, 118.7, 111.2 (q, J=32 Hz), 109.6, 36.7; HPLC ret. time: 5.759 min.
